World explorer Augustus Skinner has died! Now, his three young grandsons have inherited the old Skinner Mansion and its contents. But Grandfather Skinner also left them a big surprise — the Skinner Boys are now Guardians of the Lost Sercets, a collection of unique artifacts across the world that possess incredible powers. An even bigger surprise is in store! Grandpa Skinner also appointed a fourth Guardian, feisty teenage cousin Tara. As these boys know almost nothing about girls — she's probably their biggest challenge of all. And vice-versa. (26 x 24min)
